Seeking a therapist requires bravery and self awareness, and I applaud anyone who takes the time to recognize the need for, and reach out for support. Whether you have encountered life transitions, self-esteem issues, symptoms of anxiety and depression, or questions have arisen about your past experiences and their influence on your circumstances, I would be happy to work together to find some answers. While therapy can be part of a holistic approach to wellness, it is also individualistic, and I believe that each client deserves differentiation that will best suit their needs.
I believe that everyone has a unique story. Through empowering clients, I strive to guide them toward adaptable patterns and solutions to their challenges. My years of teaching experience has reinforced my belief that everyone deserves a differentiated approach to problem solving and well-being.
If you feel that we would work well together in a respectful and empowering collaboration, it would be my privilege to connect with you. Let’s discover your story!
